ANKARA - A worker at a Turkish statistics office in the eastern province of Kars shot dead six people before committing suicide on Wednesday, in what local media said appeared to have been a revenge attack over a professional dispute.

Kars Governor Eyup Tepe said the Statistics Institute (TUIK) employee had come to the building and had shot dead six staff including the regional manager with a Glock pistol. One other employee escaped with light injuries.

"Veysi Erim was working as a sociologist ... and was receiving treatment for psychological problems. This horrible incident has no connection with terrorism," Tepe's office said in a statement on its website. (Reuters)
